Changes to 90.1?

Staff -- Consulting-Specifying Engineer, 5/1/2006

ASHRAE has proposed that the portions of ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings, dealing with lighting be adopted in the International Energy Conservation Code published by the International Code Council.

Specific proposals:

• Address reasonable alternatives to showing compliance with line-voltage lighting track and plug-in busway lighting requirements;
• Provide additional control options for exterior lighting.
  Additional proposals from 90.1 unrelated to lighting include:
• Add a table of U-factors to match the prescriptive R-value table in the code;
• Strengthen the requirements for hot gas bypass.
• Address HVAC system completion and commissioning requirements.

The proposed changes are scheduled to be evaluated in September for possible inclusion in the 2007 IECC Supplement.
